6.108

如經說云。如有福龍。依報快樂具足。妻妾伎女衣服飲食象馬七珍無不備有。優樂自在過逾於人。乃至六欲天中亦有鳥獸。自在受樂。亦有薄福諸龍。日別熱沙爆身。為諸小蟲之所唼食。又如人間畜生驅策鞭打擔輕負重馳騁走使不得自在。乃至水陸空行乏少水草共相殘害。又復鐵圍山間。兩界畜生恒居暗瞑。受苦無間無暫時樂。如是諸苦不可具陳。

As a sūtra states: There are meritorious nāgas whose dependent retribution is fully replete with joy. Wives, concubines, singing-girls, clothing, food and drink, elephants, horses, and the seven treasures—there are none that they do not possess. Their ease, joy, and sovereignty surpass those of humans. Even among the six heavens of desire there are birds and beasts that freely experience pleasure. There are also nāgas of meager merit whose bodies are scorched daily by hot sand and nibbled and eaten by small worms. Furthermore, as with the animals in the human realm, they are driven, whipped, forced to bear light and heavy loads, and run ragged without freedom. Furthermore, those traveling on water, on land, or in the air lack water and grass and butcher one another. Moreover, between the Iron Encompassing Mountains, the animals of the two realms perpetually dwell in darkness, enduring uninterrupted suffering without a moment's joy. Such sufferings cannot be fully recounted.
